Hi Team,

I came across potential memory saving commit from Blink, which we can merge, if we can have AB test to confirm, it does benefit us.

Blink Commit: https://src.chromium.org/viewvc/blink?view=revision&revision=170497

Testcase URL (used by Blink): http://norvig.com/big.txt

WebKit Source: https://searchfox.org/wubkat/source/Source/WebCore/rendering/LegacyRootInlineBox.cpp#288

^ It is in Legacy Inline rather than IFC. So don't know how much we can benefit from it.

This compiles:

auto* layoutState = blockFlow().view().frameView().layoutContext().layoutState();
    if (layoutState->isPaginated())
        setPaginatedLineWidth(blockFlow().availableLogicalWidthForContent(heightOfBlock));

Just wanted to raise to get input and insight.

Thanks!
